Wbt/nemo UNT/TE@ STATES PATENT @FETCH CLAUDE HERBERT ABBOTT, OF LISBON, NORTH DAKOTA.

ACETYLENE-GAS GENERATOR.

Application filed December 18, 1913.

T0 all whom it may concern Be it known that I, CLAUDE HERBERT AB- BoTT, a citizen of the-United States, residing at Lisbon, in the county of Ransom and State of North Dakota, have invented certain new and useful mprovements in Acetylene-Gas Generators; and l do declare the following to be a full, clear, and exact description of the invention, suc as will enable others skilled in the art to which it apertains to make and use the same.

This invention relates to improvements in acetylene gas generators.

An bj ect is to provide an improved construction and arrangement of carbid feeding mechanism by means of which the carbid is fed to the apparatus in uniform quantities and as needed.

A further object is to provide an apparatus of this character which will besimple, strong, durable, and inexpensive in construction, eflicient, reliable and entirely automatic in operation.

1With these and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed.

1n the accompanying drawings: Figure 1 is a vertical section of my improved generator complete; Fig. 2 is a similar view o the upper portion of the generator tanlr and carbid cylinder showing the gas bell lowered and the feeding mechanism operated thereby and in position for discharging carbid into the carbid chamber; Fig. 3 is a similar view taken at right angles to Fig. 2; Figs` 4 and 5 are detail views of the carbid feeding mechanism.

My improved acetylene gas comprises a generating tank 1, the lower portion of which forms the generating chamber and is disposed beneath the surface of the ground so that the water contained therein will not freeze. The upper portion of the generator chamber 1 projects a suitable distance above the ground and forms a casing for the feeding mechanism hereinafter described. The upper portion of the generating chamber 1 above the surface o the ground is surrounded by an outer shell or casing 2 which is spaced a suitable distance from the upper portion of the generator chamber 1, said space being closed at the lower end of the shell 2 and at the surface of the ground as shown. The space begenerator Specificaton of Letters Patent.

tween the shell 2 and the upper portion of the generator chamber 1 forms an annular sealing compartment 3 which is adapted to contain oil or other non-freezing material and in which the gas bell or cover 4 of the generating chamber works. The bell or cover 4 rises and lowers in the space 3 under the pressure of the gas generated in the chamber 1 and the upward movement of the bell is limited by stop lugs 5 on the upper ends of guide rods G secured to the outer side of the shell or casing 2 and projecting a suitable distance above the same. The bell 4 has secured thereto apertured guide lugs 7 which slidably engage the guide rods 6 and which, when the bell has reached the limit of its upward movement, come into contact with the stop lugs 5 and thus prevent 4farther upward movement of the bell.

Arranged in the upper portion of the generating chamber brackets S secured to the inner side of said chamber is a casing 9 the upper portion of which forms a carbid hopper 10 having its bottom funnel shaped or inclined toward a discharge opening with which is connected a discharge spout 11. The casing 9 is of less diameter' than the upper portion of the generator 1 so that a space is left between these parts up which the gas from the generating chamber passes into the bell or cover 4.

The carbid feeding mechanism herebefore referred to comprises a cylinder 12 which is open at its ends and is revolubly mounted at a suitable angle on a supporting shaft 13 which is rigidly secured and braced at its outer end to the inner side of the casing 9 at a suitable distance below the hopper 10 and which projects upwardly at a suita le angle across the lower portion of the casing 9. The upper end of the cylinder 12 is disposed in position to receive the lower end of the carbid discharge spout 11 of the hopper 10 through which the carbid is discharged from the hopper into the cylinder. The cylinder 12 is divided into a plurality of pockets 14, three of which are preferably employed, and are arranged in staggered rclation at intervals across the cylinder. The

partitions forming these pockets extend across one half the diameter of the cylinder and the pockets formed thereby are adapted to be successively brought into position for receiving the carbid at one end of the cylinder from the discharge spout 11 and to and supported upon another of said pockets discharge the carbid from the into the generating chamber is revolved on the shaft 13 by an operating mechanism hereinafter described. The cylinder is provided with a centrally disposed eloiig'ated sleeve or socket 15 with which the shaft 13 is engaged and which is closed at its upper end and surrounded by the pockets 14 of the cylinder.

Secured to one side of the cylinder near its upper end is a laterally projecting arm 16 having on its outer end an overbalancing weight 17 which when the cylinder is in an inoperative position engages a stop finger bottoni of the hopper 10 and which when the cylinder is turned to a bring the center of gravf the weight past the pivotal support the cylinder will turn the latter half way around or to a position where the weighted arm depends or projects from the lower side of the cylinder.

The means for imparting a preliminary or starting movement to the cylinder 12 at the proper time comprises a trip rod 19 which projectsupwardly through and is slidably mounted in a sleeve or tube 20 arranged through the carbid hopper. On the upper end of the rod 19 is a right angular hook 20 which is engaged with a similarly formed hook 21 secured to the inner side of the top of the bell or cover 4 of the generating' chamber whereby when said bell or cover is raised and lowered the rod 19 will also be raised and lowered. On the lower end of the trip rod 19 is a trip linger 22 which when the trip rod is moved downwardly by the lowering of the bell 4, is brought into engagement with a trip finger 23 secured to and projecting laterally from one side of the cylinder 12 whereby the latter is turned to ay suflicient extent to bring the weight 17 past its center of gravity or past the line of the shaft 13 on which the cylinder is mounted whereupon the weight will drop and continue to turn the cylinder 12 to a half revolution as liereinbefore described.

opposite end as the `cylinder the machine while will be brought int-0 position to receive the carbid from the spout 11 of thehopper. After a charge of carbid has thus been discharged into the generating chamber more gas will be formed which will again raise the bell 4 and the trip rod 19. The lower end of the rod 19 has connected thereto a chain or other flexible element 247 the opposite end of which is connected to the cylinder 12 whereby when the latter is turned in the manner described to discharge a cliarg'e of carbid the chain will be wound on the cylinder and which when the bell 4 and the trip rod 19 are raised will be unwound from the cylinder by the upward movement of the trip rod thus revolving the cylinder in t ie reverse direction and restoring the saine to an inoperative position as shown in Fig. 1 of the drawings.

The generating chamber immediately below the ground line is connected by a gas conducting pipe 25 to a gasonieter or reservoir 2G which may be arranged adjacent to the generating' mechanism or at any desired l comprises an outer casing 27 and an inner. casing 28 which is spaced from the outer casing to form an annular sealing chamber adapted to receive i oil or other non-freezing solution. engaged with the space between the inner and outer casings 27 and 2S of the tank 26 .is a gasoineter beii 29, which, as the gas accumulates in the gasometer or reservoir will be raised and will exert the pressure upon the gas in the reservoir. ranged in the inner casing 28 of the gasometer is a suitable filter 30 to which is connected a gas conducting pipe 31, through which gas is supplied from the reservoir and conducted to the burners or other place of use. vhe pipe 25 which connects the generr-.ting chamber 'I with the gasometer or 'reservoir is provided with a three-wav valve 32 while the gas conducting pipe 31 is also Slidably snitable point.

.in the operation of the'device the hopper O issupplied with carbid through a suitably closed feed opening 34 arranged in` the upper end thereof. Assuming that the generation of gas has been started in the generating' chamber the pressure of this gas raises the bell or cover 4 of the ber and then lls the gasonieter or reservoir, passing thereinto through pipe 25. TWhen the gas in .the reservoir has been withdrawn of th in said reservoir will then be obtained through the weight of the bell or cover 4 of the generator and as the gas is continued to be drawn from the reservoir, said bell or cover 4 will lower until the trip finger 22 engagement with the trip nger 23 on the cylinder 12 thereby starting the turning movement thereof which is completed by the weight 17 in the manner described and brings one of the carbid pockets therein into position for discharging the contents thereof into the water cf the generating chamber whereby a suiiicient supply of gas` will be immediately formed and will again raise the bell 4- and then pass into the gasometer or reservoir. As the bell 4 is thus raised the feed cylinder will be turned in a reverse direction or restored to its normal position as hereinbefore e generator 186 described. rlhe weight of th required generating chani- V extent to permit the bell 29 e reservoir to lower, pressure on the gas Sil cover 4 and gas holder cover 29 are so proportioned as to produce the result above described.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the ininoi' details of construction may be resorted to without departing from the principle or sacriiicing any of the advantages of the invention as claimed.

Having thus particularly described the nature of my invention what I claim is l. In an acetylene gas generator, the combination with a generating chamber of a gas bell slidably mounted on said generating chamber, a casing arranged in said upper end of the generating chamber, a carbid hopper having a discharge spout, a feeding mechanism comprising a revolubly mounted cylinder having one end positioned to receive carbid from said spout and having therein a series of pockets adapted to be successively brought into position for receiving the carbid from the spout and for discharging the carbid into said generator chamber, an operating weight connected with said cylinder, a trip rod carried by said gas bell, a trip arm arranged on said cylinder and adapted to be engaged by said trip rod when said cover is lowered, whereby said cylinder is turned a sulicient distance to bring the weight thereon past its center of gravity whereupon the weight will continue the turning movement of the cylinder', and a chain connected with said trip rod and adapted to be unwound from said cylinder on the upward movement of said cover, whereby the cylinder is restored to an inoperative position.

2. In an acetylene gas generator the com- Gopes of this patent may be obtained for ve cents each, by addressing bination with a gas generating chamber having a bell slidably engaged therewith, of a casing arranged in said generator, a carbid hopper, a discharge spout connected with said hopper, a feeding mechanism comprising a revolubly mounted cylinder having therein a series of partitions arranged in staggered relation at intervals across said cylinder, each of said partitions extending across one half the diameter of lthe cylinder and forming a series of pockets adapted to be successively brought into position to receive the carbid from said discharge spout and to discharge the carbid into said generating chamber, and means actuated by the rising and lowering movement of said bell to operate said feeding mechanism.

3. In an acetylene gas generator the combination with a gas generating chamber having a gas bell slidably engaged therewith, of a casing arranged in said generator, a carbid hopper, a discharge spout connected with said hopper, a feeding mechanism coniprising a fixed supporting shaft disposed at a suitable angle, a cylinder open at each end and having fixed therein a sleeve adapted to receive said shaft, whereby the cylinder is revolubly supported at an inclination in l said generating chamber, a series of pockets adapted to be successively brought into position to receive the carbid from said discharge spout and to discharge the carbid into said generating chamber, and means actuated by the rising and lowering movement of said cover to operate said feeding mechanism.
